I've been a programmer for way too many years, starting by entering a program through front-panel switches on a PDP-8. (If you know what that's like, you've also been programming for too many years and we should have a beer some time.) My wife and I run a two-person company developing language learning and study apps for smart phones, as well as web-based learning activities with a game-like spin.

The competent programmer is fully aware of the limited size of his own skull. He therefore approaches his task with full humility, and avoids clever tricks like the plague. — Edsger W. Dijkstra
